Add sidebar handling #13
Description
The original theme has a configurable sidebar. This works via a CSS class on the body tag (e.g. <body class="left-sidebar is-preload">). Although it would be possible to handle this manually by the user of the theme, the body is defined in _index.cshtml. Thus the user would need to overwrite the complete layout.
Therefore another solution needs to be found. Additionally it the user of the theme should have an easy possibility to add its sidebar content. The CleanBlog theme uses a _sidebar.cshtml override for the user. This might be a good option here as well,
